本研究结合了父母和观察措施，以检查自闭症儿童（N = 67）和发育迟缓儿童（N = 42）的异常感觉特征和限制性重复行为之间的关联。实证因素分析被用来验证三个感兴趣的感觉结构：高反应性，低反应性，感觉寻求。检查三个派生的感觉因子评分和重复行为量表（修订版）评分之间的相关性，发现两个临床组中这些行为同时发生。具体来说，高水平的过度反应行为预示着高水平的重复行为，这些变量之间的关系在控制心理年龄的情况下保持不变。我们主要发现低反应性或感觉寻求与重复行为之间无显著关联，除了感觉寻求与仪式性/相同行为相关。这些发现表明，共同的神经生物学机制可能是高反应性感觉症状和重复行为的基础，并对诊断分类和干预具有意义。
This study combined parent and observational measures to examine the association between aberrant sensory features and restricted, repetitive behaviors in children with autism (N = 67) and those with developmental delays (N = 42). Confirmatory factor analysis was used to empirically validate three sensory constructs of interest: hyperresponsiveness, hyporesponsiveness, and sensory seeking. Examining the association between the three derived sensory factor scores and scores on the Repetitive Behavior Scales—Revised revealed the co-occurrence of these behaviors in both clinical groups. Specifically, high levels of hyperresponsive behaviors predicted high levels of repetitive behaviors, and the relationship between these variables remained the same controlling for mental age. We primarily found non-significant associations between hyporesponsiveness or sensory seeking and repetitive behaviors, with the exception that sensory seeking was associated with ritualistic/sameness behaviors. These findings suggest that shared neurobiological mechanisms may underlie hyperresponsive sensory symptoms and repetitive behaviors and have implications for diagnostic classification as well as intervention.
